Miwa Shibuya, a Japanese student of sustainable development has conducted fascinating research providing insight into the lives of Japanese retirees in Chiang Mai; what motivates them to spend their old age in a foreign country; why Thailand, and why Chiang Mai? What do they enjoy about it, what they don't enjoy, and what are their worries for the future - especially about the provision of care.
By way of background, the book looks at Japanese demography - Japan has the world's highest percentage of elderly.
